Specification of Letters Patent.

Application filed January 3, 1916. Serial No. 70,013.

To all whom t may concern.'

Be it knownthat I, ALMON C. BYRUM, a citizen of the United States, residing at Onida, in the county of Sully and State o-f South Dakota, have invented certain new and useful Improvements in Cultivators; and I do declare the following to be a full, clear, and exact description ofk the invention, such as will enable4 others skilled in the art to which it appertains to make and use the same.

My invention relates broadly to improvements in earth-working implements, and more particularly to an improved type of cultivator, the object of the invention being to improve upon the general construction of multiple shovel cultivators to such an extent as to not only increase the eiiiciency and durability thereof, but to render them capable of lbeing easily and cheaply manufactured.

With this general object in view, the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which- Figure 1 is a side elevation tor constructed in accordance with the invention; Fig. 2 is a rear elevation thereof; Fig. 3 is a top plan view; Fig. 4 is an enlarged top plan view of a number of the implement frames and the transverse bar to `which they are hinged; and Figs. 5 and 6 are detail sectional views showing two positions of the means for raising and lowering the `implement frames.

ln specifically describing the construc tion shown in the drawings above briefly described, similar characters will be placed on corresponding parts throughout the several views and reference will be herein made to the numerous elements by their respective indices. To this e'nd, the numeral 1 refers to an arched axle supported by wheels 2 and carrying an appropriate frame 3 equipped with a common type of tongue 4 and seat 5. Secured to the frame 3 at the front end thereof, is 'a transverse horizontal bar 6 having hooks or the like 7 at its opposite ends, said hooks being received in eyes on the front ends of a pair of draft rods 8 which incline downwardly and rearwardly and are provided with upturned `of a cultivarear ends 9 secured in sleeves or the like 10 which are rigidly secured to the front side of a transverse horizontal angle-iron bar 11, said bar being of considerable greater length than the axle 1. Rising from the upstanding flange of the bar 11 is a pair of vertically extensible and contractible hangers 12 whose upper ends are formed with eyes receiving hooks 13 on a pair of laterally extending brackets 14 secured to the frame 3 near the rear end thereof. By this arrangement of parts, it will be obvious that the bar 11 may be adjusted vertically at will, to gage the depth of cultivation, yet that the draft rods8 will always perform their functions.

Secured to the horizontal rearwardly eX- tending iiange of the angle bar 11 by bolts or the like 15, is a plurality of plates 16 whose rear ends are formed with hinge knuckles receiving therein a transverse horizontal rod 17, said rod being also passed through additional hinge knuckles on the front ends of the side bars 18 of a plurality of vertically oscillatory implement frames 19.

Four frames 19 are shown in the present embodiment of invention, said frames including the side bars 18, braces 20 connecting said side bars, and heavy transverse horizontal bars 21 whose opposite ends are loosely connected to the rear ends of the aforesaid bars 18. The connections between the bars 18 and 21 may be in any one of a number of forms, but the ends of said bars 21 are preferably socketed at 22 to receive loosely therein the rear lends of the bars 18, heavy Cotter pins or the like 23 being passed through the bars 18 in rear of said bars 2l. This form of connection is not only exceedingly simple and inexpensive, but it is elicient and allows the bars 21 to be readily removed for shipping or other purposes. question allow the frames 19 a considerable amount of torsional movement, this being expedient for a purpose to be hereinafter explained.

Disposed above the two bars 21 at one Side of the implement and having downturned ends pivoted centrally thereto, is a yoke bar 24, while pivoted at its ends to the centers of the other bar 21 is a similarly constructed yoke bar 24a, the two bars 24 and 24a being in turn connected by a third yoke`bar 25 having its ends pivoted to the Furthermore, the connections in centers of said bars. The bar is carried by the lower ends of a pair of chains or the like 26 lwhose upper ends are secured to the lower ends of a pair of arched links 27 the front ends of said links being pivoted to crank arms 28 which extend laterally from a rock shaft 29 mounted on the frame 3 and equipped with an operating lever 30. Thus, when the shaft 29 is moved rearwardly to the extent shown in Fig. 5, all of the frames 19 will be lowered, but when said shaft is rocked forwardly as disclosed in- Fig. 6, the frames in question will be raised and will be held in this position without any locking means for the shaft in question. This is due to the fact that when the frames are raised, the opposite ends of the links 27 are disposed in planes below the shaft 29 and therefore said links exert no turning tendency on the shaft in a direction to lower the aforesaid frames.

Secured on the horizontal flange of the bar 11'is an implement attaching plate 31 cast in a number of sections, each carrying a plurality7 of transversely disposed horizontal bearings 32 and upright stop lingers 33 spacedendwise from and slightly in rear of said bearings. The bearings and fingers receive therebetween the front ends of a plurality of implement drawbars 34 having laterally extending studs which project into said bearings, the fingers 33 preventing removal of said studs until the drawbars are raised sufficiently to Clear said ngers. The numerous drawbars 34 overlie the bars 21 and -are secured theretoby hook bolts or the like 35. However, when it is necessary toremove any one of the drawbars in question, releasing of its bolt 35 will allow it to be moved in the necessary manner:

The rear ends of. the drawbars 34 may carry any preferred type of earth-working implement, butv said ends are preferably curved downwardly and forwardly and equipped with flat approximately horizontal shovel blades 36 adapted to travel only slight distances below the surface of the earth.

By constructing themachine in the man# ner above defined, it will operate to great advantage, particular emphasis being' laid upon the fact that the numerous implement frames 19 may oscillate vertically independently of each other to render the machine readily operable upon uneven land. Also, due to the connections hereinbefore described between the arms 18 and bars 21,

the frames 19 may have a --considerable amount of torsional movement. This is highly advantageous to allow the shovel blades 36 to readily adjust themselves for proper engagement with uneven surfaces.

Furthermore, although the yoke bars 24, 25

and the raising means therefor will lift or lower all of the frames 19 at will, they will not interfere in any manner with the successful movement of said frames when cultivating.

F rom the foregoing description, taken in connection with the accompanying drawings, the construction, manner of operation and numerous advantages of my improved cultivator will be readily understood without' requiring a more extended explanation. In conclusion, however, I wish to state that although certain specific details of construction have been illustrated and described, numerous changes may be made within the scope of the invention as claimed without sacrificing any of the primary advantages thereof.
